Application June29, 1953, 'seaa M36451? 2 Claims. (0.229226 Thisinvention relates to a packaging device for wrapped products, that is,products which are arranged on the device and then wrapped.

The main objects of this invention are:

First, to provide a packaging device formed of paperboard which is welladapted for the packaging of sliced meats, for example, arranged orstacked in fanned relation which results in variation in the depth ofthe product.

Second, to provide a packaging device which may be quickly adjusted toerected position after the product has been arranged thereon andelfectively supports the product for wrapping and results in anattractive package.

Third, to provide a packaging device of this character with an effectivecorner closure means.

Fourth, to provide a packaging device of this character which may bevery economically produced from an integral blank or sheet ofpaperboard.

Objects relating to details and economies of the invention will appearfrom the description to follow. The invention is defined and pointed outin the claims.

A preferred embodiment of the invention is illustrated in theaccompanying drawing, in which:

Fig. l is a perspective view of a package embodying the packaging deviceof my invention.

Fig. 2 is an enlarged fragmentary view of the erected device prior toapplication of the wrapper thereto.

Fig. 3 is an enlarged fragmentary view in section on a linecorresponding to 33 of Fig. 2.

Fig. 4 is a plan view of the device in the flat.

Fig. 5 is a fragmentary perspective view illustrating certain steps inthe erection of the device.

Fig. 6 is a fragmentary perspective view of a modified form orembodiment of my invention.

In the specification and claims I use the term side" and end for thesake of brevity and convenience description. It will be understood thatthe packaging may be substantially square, as is illustrated in Fig. l,or it may be elongated, this depending upon the quantity and characterof the packaged material.

The packaging device of my invention is formed of an integral sheet ofpaperboard cut and scored to provide a bottom panel 1 and side and endwalls 2 and 3 respectively. These walls are angularly disposed asdistinguished from being opposed. The side and end Walls are hingedlyconnected to the bottom panel as by the scores 4 and 5.

A top member 6 is hingedly connected to the side wall 3 as by thescoring 7 and a top member 8 is hingedly secured to the end wall 2 as bythe scoring 9. The end 10 of the end wall 3 is substantially spaced fromthe hinging connection 4 of the side wall 2 to the bottom panel as isclearly illustrated.

The end 11 of the top member 8 is substantially in alignment with thehinging connection 4 for the side walls to the bottom panel so that theend top member does not project beyond the side wall 2 when thepackaging device is erected and so that the end top member may bejfolded-within the side top member, as is best shown in vFig. 2.

To facilitate erecting the end edge of the end top member is beveled orcut away at 12. The side top member .6 provided with an end closure flap13 hingedly connect'ed theretoat 14. This is desirably tapered inwardlyas viewed in thelliilank.v

In the embodiment shown in Figs. 1 to 5 inclusive a slit is formed onthe .hin'ging line 9 for the top mem- '8 to the end wall and a slit 16is formed on the gmgline 14 forthe closure member 13. I when inere'cted'position, as shown in Fig 2, the end wall 3 overlaps theclosure flap '13 holding it in erected position. The slits 15 and 16provide for interlocking engagement of the end top member 8 with theclosure member 13 with the end wall on the outer side and the edgeportion of the end top member engaging the inner side of the closuremember so that the parts are efiectively locked in erected position. Inerecting the tongue-like end portion of the end top member in theembodiments of Figs. 1 to 5 is disposed below the side top member. Thisinterlocking engagement described also holds the side top member inerected position.

In the embodiment shown in Fig. 6, the interlocking engagement of thetop and side top member is modified. The end top member 17 of thisembodiment has a tonguelike extension 18 engageable through a slit 19formed in the side top member 20. In this embodiment the side wall 2 isomitted.

In 'both embodiments the device may be very quickly erected to receivethe wrapper indicated at 21. Desirably the side top flap has a diagonalscore 22 at its end opposite its closure flap 13 and the end top member8 has a diagonal score 23 opposite its end 11. The purpose of thesescores is to allow the top members to more readily conform to thematerial packaged.

The packaging device of my invention is well adapted for packagingsliced meat such as, for example, sliced bacon which is arranged infanned stacked relation for display purposes. This results in thevariation in thickness of the packaged material particularly toward oneedge thereof. The packaged material is arranged on the bottom panel andthe side and end walls swung upwardly and the top members swungdownwardly upon the material. The side wall 2 may be swung to aninclined position which allows conforming to the edge of the materialpackaged.

I have illustrated and described my invention in a highly practicalembodiment thereof. I have not illustrated or described otheradaptations or embodiments which I contemplate as it is believed thatthis disclosure will enable those skilled in the art to embody or adaptmy invention as may be desired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. A packaging device formed of an integral blank of paperboard cut andscored to provide a bottom panel, angularly disposed relatively narrowside and end walls hinged to the side and end edges of the bottom panel,the end wall terminating in substantially spaced relation to the hingeconnection for the side wall to the bottom panel, side and end topmembers hinged to the upper edges of the side and end wallsrespectively, the end of the end top member adjacent the side top memberbeing substantially in alignment with the hinge connection for the sidewall to the bottom panel, the end top member being beveled from the endthereof to the end of the end wall, the side top member having a taperedclosure flap hingedly connected to the end thereof and foldabledownwardly in overlying relation to the bottom panel when the side topmember is in erected position, the end wall when erected overlapping theinner end of said datented July 24, 1956 weet A closure flap to saidside top member and opening at the end edge thereof, and a slit on thehinging line ofthe end top member to the end wall, saidslitsdefining'relatively flexible portions facilitating the overlappingengagement of the side and end top members when in erected position.

2. A packaging device formed of an integral blank of the end wallterminating in substantially spaced relation to the hinging connectionfor the side wall to the bottom panel, side and end top members hingedto the-upper edges of the side and end walls respectively, the side topmember having a downwardly foldable closure flap hingedly connected tothe end thereof, the end wall when erected engaging said closure flapfor holding it in erected! position, there being a slot on the hingingline of said closure flap to said side top member and opening at the endedge thereof, and a slitwon the hinging line of the end top member tothe end wall, said slits defining rela tively flexible portionsfacilitating the overlapping engagement of the side and end top memberswhen in erected position.
